The Sudoku book is currently scheduled to come out around November. Oxford University Press releases e-editions of all their books, but I think the Sudoku book may not fare too well in that form. The book is very diagram heavy and has lots of original puzzles for solving.

You’re too kind.

Somewhere in between! The finished book will probably be in the 250-300 page range.

Thanks! It will be a little while yet before the book actually appears. I’m first handing in the manuscript on May 1, and then it will take a while to turn it around. So we’re looking at early 2012 as a publication date. Right now it’s in the hands of various proofreaders.
